Taiwan 2026 Local Elections: Foreign Interference, Cyberattacks and Deepfakes — What Officials and Campaigns Have Reported
Ahead of Taiwan's nationwide Nine-in-One local elections on November 28, 2026, Taiwan's National Security Bureau, a mayoral campaign and politicians from both major parties have published figures, reported incidents or filed complaints regarding cyber operations, disputed online content, and artificial intelligence-generated media. This briefing compiles official disclosures from the National Security Bureau (NSB), cross-party complaints filed at prosecutors' offices, and statutory defense mechanisms under Taiwanese election law in a neutral, attributed reference format.
Latest Update: National Police Agency Figures (November 4, 2026)
On November 4, 2026, the National Police Agency (NPA) held a press conference titled "Combatting Election Disinformation and Transnational Repression," hosted by NPA Deputy Director-General Kuo Shih-chieh (郭士傑) with case briefings delivered by Criminal Investigation Bureau (CIB) Commissioner Chiu Shao-chou (邱紹洲) (UDN, Nov 4, 2026; Taiwan News, Nov 4, 2026). According to the NPA, law enforcement agencies across Taiwan had accepted and investigated election disinformation cases through October 31, 2026 (CNA, Nov 4, 2026).
According to the Criminal Investigation Bureau, election disinformation has spanned text, image, and audiovisual materials, including AI-synthesized content, with nearly 70 percent transmitted online (UDN, Nov 4, 2026). Among the seven deepfake cases accepted and being investigated by police, reported incidents include a manipulated image titled "Wan-an Eliminates the Three Evils" (萬安除三害) targeting Taipei Mayor and Kuomintang (KMT) candidate Chiang Wan-an (蔣萬安), and a synthetic video falsely depicting Democratic Progressive Party (DPP) Changhua County magistrate candidate Chen Su-yueh (陳素月) saying things she never uttered (UDN, Nov 4, 2026). The CIB stated that, as of October 31, no candidate had yet applied for paid forensic examination under the Civil Servants Election and Recall Act (UDN, Nov 4, 2026).
The NPA noted that candidates who discover deepfake video or audio targeting themselves may apply to the CIB for forensic examination at their own expense from the election proclamation date of August 20 until November 27, the day before voting day, under the Civil Servants Election and Recall Act (CNA, Nov 4, 2026; Taiwan News, Nov 4, 2026). Candidates suspecting criminal violations may file a police report with the relevant recordings attached and submit takedown reports to online platforms (CNA, Nov 4, 2026). CIB Commissioner Chiu Shao-chou stated that using AI deepfakes to disseminate false information carries aggravated criminal penalties of up to seven years' imprisonment, according to FTV (FTV News, Nov 4, 2026).
The NPA reported that election-interference tactics used by external forces have continued to diversify ahead of the vote (CNA, Nov 4, 2026; Taipei Times, Nov 5, 2026):
- Election betting manipulation: Manipulating illegal election betting pools (How Taiwan's election betting law works).
- Sponsored trips to China: Sponsoring trips to China for Taiwanese citizens.
- Donations via Taiwanese businesspeople: Channeling campaign donations through Taiwanese businesspeople, including hosting banquet events.
- Temple and religious mobilization: Using temple and religious activities for organizational mobilization and soliciting local grassroots figures.
Regarding transnational repression, the NPA reported investigating nine cases suspected of involving external forces colluding with domestic and foreign gangs, unscrupulous private detective agencies, foreign individuals, and local collaborators (UDN, Nov 4, 2026; Taipei Times, Nov 5, 2026). Prosecutors have indicted defendants in four of these cases, while five remain under active investigation, according to FTV (FTV News, Nov 4, 2026). The four indicted cases announced by police comprise: the paint-splashing incident at Comedy Club (卡米地喜劇俱樂部遭潑漆案); the physical assault on Yaita Akio, CEO of the Indo-Pacific Strategic Think Tank (印太戰略智庫執行長矢板明夫遭毆打案); the covert trailing and filming of DPP Taipei mayoral candidate Puma Shen (民進黨台北市長候選人沈伯洋遭跟拍案); and the staged car accident causing injury to crosstalk performer Huang Yi-hao (相聲演員黃逸豪遭假車禍傷害案). According to the NPA Security Section, operational forms identified across these external-force cases include harassment such as paint-splashing or firecrackers, threats, violent assault or staged car accidents, and tailing or covert surveillance (UDN, Nov 4, 2026).
Note: InfoMiner Election Lab does not independently verify these National Police Agency statistics, reporting official law enforcement disclosures strictly as attributed data points.
1. Key Figures from the National Security Bureau's October 2026 Legislative Report
On October 20, 2026, the National Security Bureau (NSB) delivered a written operational report to the Legislative Yuan ahead of scheduled testimony by NSB Director-General Tsai Ming-yen (蔡明彥) before the Foreign Affairs and National Defense Committee on October 22 (CNA, Oct 20, 2026; Taipei Times, Oct 21, 2026). The document detailed network intrusion attempts and online controversial information collected across the first nine months of 2026:
- Daily Intrusion Average: The NSB reported that through September 2026, the Government Service Network was targeted by an average of approximately 2.58 million intrusion attempts per day (CNA).
- Upward Trajectory Since June: Intrusion frequency displayed an upward trend beginning in June 2026.
- July Peak of 185.6 Million: In July 2026, detected cyberattacks surged past 100 million to reach 185.6 million, an amount exceeding the sum of all attacks recorded during the entire first quarter of 2026 (Taipei Times).
- Suspected Preparatory Objective: The NSB said it cannot rule out that the rise is preparation (intelligence-gathering and intrusion) to interfere in the Nine-in-One elections (CNA).
- 2.50 Million Posts Tracked: By tracking abnormal accounts between January and September 2026, intelligence teams collected approximately 2.5 million posts containing controversial or disputed information (CNA).
- 48% Year-on-Year Growth: This volume represented a 48 percent increase compared to the approximately 1.69 million posts collected during the identical period in 2025 (Taipei Times).
- Platform Concentration: Posts were primarily observed across Facebook, online discussion forums, Threads, and YouTube.
- Platform Shifts: The NSB noted significant proportional increases on Facebook (rising from 43.6% to 68.9% of tracked disputed posts) and Threads (increasing from 4.5% to 9%).
| Indicator | 2025 Baseline / Q1 Context | Jan–Sep 2026 Reported Value | Platform / Scope Details | Attribution & Source |
|---|---|---|---|---|
| Disputed Online Posts | 1.69 million posts (Jan–Sep 2025) | 2.50 million posts (+48%) | Facebook (68.9%), Threads (9%), Forums, YouTube | NSB written report (CNA; Taipei Times) |
| Daily GSN Cyberattacks | Upward trend since June 2026 | 2.58 million / day | Taiwan Government Service Network (GSN) | NSB written report (CNA) |
| July GSN Cyberattack Peak | Exceeded total Q1 2026 cyberattacks | 185.6 million attacks | Surged past 100M threshold during July 2026 | NSB written report (Taipei Times) |
According to the NSB report (Taipei Times), AI is used across stages of attacks including probing for weaknesses, target seeking, searching for zero-day exploits and malware attacks via e-mail.
2. Interference Tactics Identified by the National Security Bureau
In its written submission to the legislature and subsequent testimony by Director-General Tsai Ming-yen on October 22, 2026, the NSB described specific operational methods, targeted domestic subjects, and delivery mechanisms the bureau attributes to China (CNA, Oct 20, 2026; Taipei Times, Oct 23, 2026):
Domestic Wedge Issues & Narrative Setting
The NSB reported that from January to September 2026, Chinese operations disseminated disputed information focused on domestic policy controversies—specifically energy, food safety, and national defense—with the suspected intent of disrupting government administration.
The NSB reported that operations also hyped specific candidates' policy proposals, public images, and the quality of local public infrastructure, aiming to shape local electoral outcomes.
Amplification Infrastructure & AI Integration
According to the NSB, narrative frameworks are frequently established by Chinese official bodies or state-run media, then amplified through proxy accounts, cyber armies (trolls), and commercial public relations agencies.
Tactics include content farms, clone websites, artificial intelligence-generated audio and video, fabricated social media accounts, and comment-section flooding. Operations monitor major news events, candidate platforms, election trends, and polling data to formulate cognitive warfare strategies, expanding the use of AI for information manipulation (CNA).
Targeted Demographic Groups & Financial Inducements
On October 22, 2026, NSB Director-General Tsai Ming-yen stated that election interference efforts in Taiwan are shifting toward specific demographic groups (Taipei Times, Oct 23, 2026). The bureau described several suspected practices:
Director-General Tsai stated that the NSB is utilizing artificial intelligence tools to trace the origins of disinformation, collecting evidentiary records of suspected interference, and hopes to hand materials over to judicial authorities before the November 28 elections.
3. Publicly Reported Campaign Incidents & Judicial Complaints
During the 2026 campaign cycle, a DPP campaign reported cyberattacks, and politicians from both the KMT and DPP have filed complaints or announced possible legal action over AI-generated media. These matters are listed below in chronological and attributed order:
On October 29, 2026, NSB Deputy Director-General Chen Sung-chi (陳松吉) informed the Legislative Yuan's Foreign Affairs and National Defense Committee that the NSB is investigating suspected cyberattacks originating from China that targeted Democratic Progressive Party (DPP) Taipei mayoral candidate Puma Shen (沈伯洋) (Taipei Times, Oct 30, 2026; CNA, Oct 29, 2026). Chen stated that the investigation could lead to criminal charges against those found responsible.
According to Shen's campaign office and CNA reporting, several websites deployed by the campaign faced planned intrusions beginning on October 23, 2026, comprising two distinct attack incidents:
- Host Server Permission Breach: In the first incident, according to the campaign office, attackers exploited a flaw in the website's upload function and gained administrative access to the host server, created fake administrator accounts and installed back doors (remote-control programs); they then tried and failed to obtain access to the main campaign website / internal system, because that system and its log-in credentials were not on the compromised server.
- Traffic Flooding on Motorcade Route Sign-Up Platform: In the second incident, overseas IP addresses flooded a platform created for supporters to sign up for (claim) sections of the campaign's motorcade route ("洋流車掃認領路段網站"). Within an hour of launch, it received more than 70,000 fake sign-ups / authentication-code requests from overseas IP addresses, per the campaign; the campaign then required log-in to sign up, which halted the automated submissions.
On August 3, 2026, Central News Agency reported that candidates and elected officials from both the DPP and KMT filed complaints against each other at the Taiwan Taipei District Prosecutors Office over suspected AI-generated audio (CNA, Aug 3, 2026):
- Complaint by Chang Ming-yu (DPP): DPP Taipei City Councilor candidate Chang Ming-yu (張銘祐) filed a complaint alleging that Taipei Mayor Chiang Wan-an (蔣萬安, KMT) was involved in abetting the production of the video 「油不得你」 (a Taipei City Government public-health video on the carcinogen benzo[a]pyrene, according to the city spokesperson's description in CNA), which was suspected of using artificial intelligence to synthesize the voice of President Lai Ching-te (賴清德).
- Counter-Complaint by Yang Chih-tou (KMT): KMT Taipei City Councilor Yang Chih-tou (楊植斗) responded by filing a criminal complaint against Tainan Mayor Huang Wei-che (黃偉哲, DPP) and DPP Legislator Wang Ting-yu (王定宇). Yang argued that Huang and Wang, during a press briefing, presented audio suspected of deepfaking the voice of Mayor Chiang Wan-an.
- Law Enforcement Action: The Criminal Investigation Bureau received a complaint that the video was suspected of using AI to synthesize President Lai's voice, possibly constituting document forgery, and referred it to Taipei prosecutors. Prosecutors opened a case under 他字案 (a preliminary case docket).
- Campaign & Official Positions: Mayor Chiang Wan-an previously stated that the allegations were intended to produce a chilling effect. A Taipei City Government spokesperson stated that artificial intelligence is a tool that should never be used for fraud or to harm people, but questioned what was wrong if it was used for health education videos on the carcinogen benzo[a]pyrene (BaP). Mayor Huang Wei-che and Legislator Wang Ting-yu stated that their public demonstration of audio files was aimed at alerting society to the risks AI deepfakes pose to personal character rights and information security.
On April 28, 2026, CNA reported an election dispute regarding alleged synthetic imagery in New Taipei City (CNA, Apr 28, 2026):
- Lee Shu-chuan Campaign Statement: The campaign office of Kuomintang (KMT) New Taipei mayoral candidate Lee Shu-chuan (李四川) stated that an online illustrator had posted a deepfake image to smear him, adding that the office had gathered evidence and was planning to file a lawsuit.
- Su Chiao-hui Office Response: The campaign office of Democratic Progressive Party (DPP) New Taipei mayoral candidate Su Chiao-hui (蘇巧慧) responded that the campaign team had never attacked opponents, had not issued press releases or held press conferences to do so, and had never authorized any internet users or social media fan pages to conduct electoral attacks.
4. Debate Over the "Cognitive Warfare" Framing
Public discussions surrounding foreign interference and cognitive warfare have generated divergent perspectives between security officials and opposition spokespersons:
The NSB's report describes cognitive warfare operations it attributes to China: according to the NSB, these operations use proxy accounts, troll networks, content farms, and AI synthesis to amplify domestic wedge issues (such as energy, defense, and food safety); the NSB said the disputed information aimed to disrupt government administration (干擾政府施政) and influence the Nine-in-One elections (CNA, Oct 20, 2026).
DPP candidate and lawmaker Puma Shen has stated that cognitive warfare refers to conduct between states (UDN, Oct 1, 2026).
On October 1, 2026, KMT spokesperson Liu Tsai-wei (柳采葳) publicly critiqued this characterization (UDN, Oct 1, 2026). Liu stated that Puma Shen uses academic definitions externally to pose as virtuous, but internally wields the national security label against domestic citizens, blaming the Chinese Communist Party whenever questioned.
Liu argued that this dynamic constitutes a partisan "green firewall" (綠色防火牆) used by the DPP to deflect domestic accountability. She stated that public grievances regarding domestic concerns—such as air pollution, vaccine shortages, and egg shortages—were labeled as Chinese narrative operations.
5. Statutory Tools: Deepfake Takedowns & Survey Blackout Rules
Taiwan's electoral legal architecture includes specific provisions regulating synthetic media during election campaigns and establishing statutory quiet periods for public opinion polling:
Under Article 51-3 of the Civil Servants Election and Recall Act (Laws & Regulations Database), statutory mechanisms apply from the election proclamation until the day before voting day:
- Legal Definition: A deepfake is defined as a computer-synthesized or other technological false depiction of a person's words or actions sufficient to lead others to believe it is true.
- Police Forensic Step: A candidate who identifies deepfake audio or video of themselves broadcast on radio, television, or the internet may apply to police authorities for forensic examination.
- Written Request: If police forensic examination confirms the material is a deepfake, the candidate may submit a formal written request to the broadcaster or platform operator, copying the relevant election commission.
- Mandatory 2-Day Removal: Broadcasters must stop broadcasting, and platforms must restrict access, remove or take down the content, within 2 days of receiving the request.
- Record Retention: Platforms and broadcasters must retain all relevant data and logs for 6 months from receiving the request (extended to 3 months after a final judgment if litigation occurs).
Under Article 53, Paragraph 3 of the Civil Servants Election and Recall Act, public opinion surveys are subject to strict pre-election publication restrictions:
- Blackout Window: From 10 days before voting day until the close of polling, parties and any person may not publish, report, distribute, comment on or cite poll data on candidates or the election by any means.
- 2026 Timing: The blackout takes effect from November 18, 2026 at 00:00 until November 28, 2026 at 16:00 (Taipei time).
